Switzerland will pay its first 13th AHV old-age pension in December 2026. The Federal Social Insurance Office’s November 3 guide estimates that about 2.6 million pensioners will receive the payment. For a person entitled to an old-age pension in December, it is paid automatically with the ordinary December pension. Its amount is based on the old-age pensions paid during the whole calendar year.
There are three questions to separate. Who qualifies in December? Which payments enter the calculation? When will the money reach the recipient? The federal guide answers the first two. The Swiss Compensation Office’s schedule gives the date it plans to issue payment instructions, which can differ from the day a credit appears in an account. The separate November referendum concerns how the extra pension will be financed.
Who qualifies in December
The payment belongs to the Swiss first-pillar old-age pension. In German it is usually described as the 13. AHV-Rente. The federal office says the eligibility test is entitlement to an old-age pension in December. It describes the extra amount as an annual addition to that month’s payment. The December test and the annual calculation do different jobs. The first identifies who gets it. The second determines the amount for someone who qualifies.
The same office says survivors’ pensions paid to widows, widowers and orphans, and pensions paid under invalidity insurance, continue on a twelve-payment schedule. The distinction is the type of pension on the recipient’s record. Someone who receives a payment described simply as a pension in a bank statement should check the benefit name on the compensation office’s documents before applying the old-age formula.
The payment is automatic for eligible old-age pension recipients. The office responsible for calculating and paying it is the AHV compensation office that pays the December pension. A recipient whose circumstances changed during the year can use that office’s records to establish which monthly amounts were actually paid. The federal office says a precise calculation is possible in December because the pension can change before then.
Why the formula uses the year’s payments
Add up the qualifying old-age pension paid during the year and divide the sum by twelve. If the monthly amount was the same for all twelve months, the result equals one of those months. If the amount changed or payments began partway through the year, the result can differ from the ordinary December amount. The formula still uses twelve as its divisor.
For a simple hypothetical example, consider an old-age pension of CHF 1,800 paid in each of the twelve months. The qualifying total is CHF 21,600. Dividing by twelve gives CHF 1,800. Under the same assumptions, the two amounts paid together in December would add up to CHF 3,600. This example illustrates the formula and uses an invented pension amount.
Now consider someone whose old-age pension starts in July and is CHF 1,800 for each month from July through December. The six payments add to CHF 10,800. One twelfth is CHF 900. The ordinary December pension is still CHF 1,800, but the extra payment reflects six months in the year. Dividing the annual total by six would calculate the average amount paid in those months, which is a different calculation.
A change in amount during the year calls for the same approach. Suppose a person is paid CHF 1,500 in each of the first six months and CHF 1,700 in each of the last six months. The first part contributes CHF 9,000 and the second CHF 10,200. The sum is CHF 19,200, which gives an extra payment of CHF 1,600. The federal office says the amount is rounded to whole francs. The examples use round figures so the order of the calculation is clear.
Which amounts belong in the annual total
Use the qualifying old-age pension amounts for the calculation. The federal guide lists child pensions and other additional pensions among the amounts excluded from the base. It also excludes the AHV 21 supplement for women in the transitional generation. These amounts can appear alongside an old-age pension in the same set of records. Their proximity does not make them part of the formula.
For example, suppose someone has an eligible old-age pension of CHF 1,650 per month and receives an excluded supplement of CHF 120 per month throughout the year. For this calculation, the eligible annual total would be CHF 19,800. Dividing by twelve gives CHF 1,650. Adding the supplement to each month would give a different result, CHF 1,770, because it answers a different question about the overall amounts paid. This example is illustrative and assumes the supplement is one of those the federal guide expressly excludes.
A useful way to organise the calculation is to keep the pension statement separate from the bank statement. The bank statement establishes what was credited. The pension statement can identify the components. If a single credit contains more than one component, the amount on the bank statement is less useful for deciding what enters the formula. Use the breakdown to distinguish qualifying amounts from any other benefits or supplements.
The date a payment is ordered and the date it arrives
The federal guide says the first payment will be made at the start of December 2026 along with the December old-age pension. The Swiss Compensation Office publishes a timetable for when it issues payment orders. Its timetable lists December 7, 2026 for the December order and says the recipient receives the payment some days after the order is issued. That schedule is useful for distinguishing the administrative step from the arrival of funds.
The date in the timetable belongs to the office named on the page. A recipient can confirm which compensation office pays their pension before applying that date to their own case. If the published order date passes and an account statement still shows no credit, first establish what the timetable actually measures. The order date alone does not establish that an individual payment has arrived.
There is also a difference between the month for which a pension is paid and the day it appears. The Swiss Compensation Office says its payments cover the current month. The December entitlement and the December payment record remain the relevant entries for the extra pension even if a payment instruction and the final bank credit carry different dates.
How supplementary benefits are treated
The federal guide expressly excludes the 13th old-age pension from countable income in the calculation of supplementary benefits, known in German as EL. The extra pension is therefore protected from causing a reduction or cancellation of supplementary benefits on that basis. This rule concerns how that payment is treated in the EL calculation. Other changes in a person's circumstances can still have their own effect on a benefit assessment.
A recipient who sees an extra payment on a statement can identify the amount and the benefit name before comparing it with a separate EL decision. The December payment record describes the pension, while the EL decision applies the rules for that other benefit. If something appears inconsistent, the distinction helps the recipient explain the question without assuming that one entry represents both calculations.
This rule also differs from the exclusions used to work out the amount of the 13th pension. Leaving a child pension out of the annual base is part of calculating the extra old-age payment. Leaving the extra old-age pension out of countable EL income is part of calculating another benefit. Both are exclusions, and they operate at different stages.
What the guidance says about recipients abroad
The federal office says Swiss nationals entitled to the December old-age pension can receive the extra payment regardless of where they live. It describes a different framework for other nationals, for whom pension export depends on applicable agreements. Where the old-age pension is exported, the guidance says the extra pension is exported as well.
Residence abroad therefore introduces a question about whether the underlying pension is payable abroad under the applicable rules. The December entitlement remains relevant. A person can start by checking the decision for their regular old-age pension and then asking the office that handles their payment whether any change in residence or circumstances affects the record used for December.
The funding vote answers a separate question
The Federal Social Insurance Office’s reform overview lists the December payment and the vote on additional financing as separate items. The payment was scheduled for December 2026. The funding proposal was scheduled for a vote on November 29, 2026 and concerned a 0.4-percentage-point increase in value-added tax to help fund the benefit. The implementation guide says the proposal would apply from 2028 if approved. A description of the proposed measure gives no result before the vote.
The distinction is useful when two reports refer to the same pension. A payment guide describes the recipients, timing and calculation. An account of the vote describes a proposed source of funding. Someone checking their December entitlement should use the payment guide. Someone looking for the outcome of the vote would need an official result after November 29. The dates serve different purposes even though both topics have the same benefit name.
Put the figures beside the records they describe
The estimate of 2.6 million recipients describes the planned reach of the first payment. It does not tell you the size of an individual pension. Likewise, the number of pensioners expected to receive it does not tell you how many received the same old-age pension amount for every month of the year. A recipient’s own month-by-month record supplies the relevant figures for the calculation.
To read that record, start with the December entry to confirm the type of benefit. Then list the qualifying amounts from January through December. Where a month contains no old-age pension payment, there is no amount from that month to add. Where the amount changes, use the figure recorded for that month. Add the eligible amounts first, divide once, and apply the whole-franc rounding to the result as described in the guide. Working with the annual sum avoids carrying rounded monthly shares into the final arithmetic.
It is also worth labelling a calculation made ahead of December as an estimate. Someone could total the months already paid and project the same amount through year-end, but the projection relies on the remaining payments staying the same. If a pension changes in December, the office will use the actual qualifying amounts. The difference between an estimate made in November and an office calculation in December can therefore reflect a different input, even though the formula stayed the same.
Which office handles which question
For a question about entitlement or the breakdown of the December pension, the federal guide points to the compensation office paying that pension. For a question about a scheduled payment order, use the relevant office’s timetable. For a question about the referendum, use the federal voting information. Starting with the document that matches the question makes it easier to keep a payment, a calculation and a funding proposal separate.
A practical example is a recipient who began receiving a pension in July and expects the extra payment to equal the latest monthly amount. The month-by-month calculation explains why it may be lower. Another recipient may see an order date online and expect the money that day. The order timetable explains why the credit date can be later. In both cases the first step is to match the published number to what it actually measures before checking the individual statement.

The December payment in one calculation
The first extra AHV pension is due with the December 2026 old-age pension. For a recipient entitled in December, the extra amount is one twelfth of the year’s qualifying old-age pension payments, rounded to whole francs. Excluded supplements are left out of that total. The office paying the December pension handles the calculation and can explain the components if the amount differs from a recipient’s estimate.
